The two MX sites are connected via third party MPLS.  The problem is when
one MX site loses Internet connectivity the sending MTA may take up to 4
hours to resend and hopefully the DNS coin toss gives it the address of the
site that is still connected.  (Read as: French ISPs don't seem as robust
as I'm use to in the US.)  Since our mail traffic is international
something like anycast would be nice.  Now the other problem is we don't
have an ASN or do external BGP ourselves.

And not that it matters in a network sense, but this is a Domino mail
system.  I'm just trying to bring it up to year 2000 standards.
